The disclosures of aforementioned applications are incorporated by reference herein in their entireties and for all purposes.

BACKGROUND

An important part of many manufacturing operations is the joining of structures that are separately prepared into larger pieces, which may themselves be joined to other structures or may be the final assembled parts. Joining of structures is a critical operation because subsequent failures may occur at the locations where structures are joined or because there may be special requirements to be met at the interface between two structures. The surface along which two structures are joined must therefore be strong, resistant to failure by many different mechanisms, such as fatigue and corrosion, and additionally meet other requirements. Epoxy resins and their composites are routinely used in joining structures in manufacturing industries to achieve these goals.

Multifunctional epoxy resins are the backbone of the rapidly growing aerospace and composite industries. In addition, epoxy resins are also used in encapsulating semi-conductors, in coatings, in paints, and in forming Interpenetrating Polymer Networks (IPNs). The degree of functionality (number of epoxy groups per molecule) of an epoxy resin is critical in determining its final properties and its end-use applications. In addition, the cost of the monomer production and the viscosity of the resin also influence its applicability. Accordingly, there is a need for the production of new resins with enhanced functionality and improved toughness which can be used in a wide variety of industrial applications.

Exemplary compounds represented by formula II include, but are not limited to:

In some embodiments, a method for preparing compounds described herein may include: (a) contacting a phenolic compound with a formaldehyde or paraformaldehyde to form a hydroxymethyl compound; and (b) contacting the hydroxymethyl compound with an epihalohydrin compound, a diethanolamine compound, or an ammonia to form the compound described herein.

In some embodiments, contacting the phenolic compound with the formaldehyde or paraformaldehyde is performed in the presence of a basic catalyst. Specific examples of the basic catalyst include alkali metal hydroxides, such as KOH, LiOH, NaOH, and the like. Non-limiting examples of phenolic compounds that may be used are phenol, bisphenol A, bisphenol F, bisphenol S, bisphenol sulphone, bisphenol sulfoxide, bisphenol chloral, bisphenolvinylidene dichloride, and bisphenol methylenedifluoride. The phenolic compound and the formaldehyde or paraformaldehyde may be reacted in a molar ratio from about 1:3 to about 1:5, about 1:3 about 1:4.5, or about 1:3 to about 1:4. Specific examples include about 1:5, about 1:4, about 1:3.5, about 1:3 and ranges between any two of these values (including their endpoints). During the reaction of the phenolic compound and the formaldehyde or paraformaldehyde, the pH of the solution may be maintained between about pH 8 to about pH 10, about pH 8 to about pH 9.5, about pH 8 to about pH 9, or about pH 8 to about pH 8.5. Specific examples include about pH 8, about pH 8.5, about pH 9, about pH 9.5, about pH 10, and ranges between any two of these values (including their endpoints).

During the reaction of the phenolic compound and the formaldehyde or paraformaldehyde, the phenolic compound and the formaldehyde may be heated to a temperature of about 50° C. to about 70° C., about 50° C. to about 65° C., or about 50° C. to about 60° C. Specific examples also include about 50° C., about 55° C., about 60° C., about 65° C., about 70° C., and ranges between (and including the endpoints of) any two of these values. The heating may be performed for about 2 hours to about 6 hours, for about 2 hours to about 5 hours, for about 2 hours to about 4 hours, or for about 2 hours to about 3 hours. Specific examples include about 2 hours, about 3 hours, about 4 hours, about 5 hours, about 6 hours, and ranges between (an including the endpoints of) any two of these values.

However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (for example, “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (for example, the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, and so on” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, and so on). In those instances where a convention analogous to “at least one of A, B, or C, and so on” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, and so on). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, and so on. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, and so on. As will also be understood by one skilled in the art all language such as “up to,” “at least,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

Various of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
